No Nukes in Space

Since the late 1980's journalism professor Karl Grossman has been writing about nuclear power in space. He was one of the founding members of the Global Network Against Weapons & Nuclear Power in Space when it was created in 1992. Today he remains on the organization's Advisory Board.

Karl's latest article, released today, comes just a day after another rocket launch failure at Cape Canaveral in Florida.

Featured on CounterPunch Karl's article is entitled A Planetary Risk: The Perils of Nuclear-Powered Space Flights. Below are a few excerpts from the piece and the full article can be read here.

NASA has released a study claiming there is a need for continued use of plutonium-energized power systems for future space flights. It also says the use of actual nuclear reactors in space “has promise” but “currently” there is no need for them.

The space plutonium systems—called radioisotope thermoelectric generators (RTGS)—use the heat from the decay of plutonium to generate electricity in contrast to nuclear reactors, usually using uranium, in which fission or atom-splitting takes place.

Examples of the use of benign power in space include the successful flight in May of a solar-powered spacecraft named LightSail in a mission funded by members of the Planetary Society. Astronomer Carl Sagan, a founder of the society, was among those who have postulating having a spacecraft with a sail propelled through the vacuum of space by the pressure of photons emitted by the sun. LightSail demonstrates his vision.

NASA Administrator Charles Bolden, a former astronaut
and Marine Corps major general, remains a big booster of using
nuclear-propelled rockets to get to Mars. Work on such a rocket has been
going on at NASA’s Marshall Space Flight Center. NASA on its website says that a nuclear-powered rocket “could propel human explorers to Mars more efficiently than conventional spacecraft.”

Through the years, NASA has worked closely with the
U.S. Atomic Energy Commission and after the commission was disbanded its
successor, the Department of Energy, on space nuclear programs. And
there’s a program at DOE’s Los Alamos National Laboratory to develop a
“robust fission reactor prototype that could be used as a power system
for space travel,” according to Technews World.

This is occurring despite Russia now abandoning its development of
nuclear-propelled rockets for missions to Mars, a project it had earlier
much-heralded. Reported TASS in April:

“Russia’s space agency Roscosmos is planning to shut down
works on developing a megawatt-class nuclear propulsion system for
long-range manned spacecraft.”

“We’ve known for years that the nuclear industry has
taken control of the seats at the NASA and DOE planning committees that
decide whether solar or nuclear power should be used on space missions,”
said Bruce Gagnon, coordinator of the Global Network Against Weapons & Nuclear Power in Space.
“The nuclear industry views space as a new market for their deadly
product. Nuclear generators on space missions, nuclear powered mining
colonies on Mars and other planetary bodies and even nuclear reactors on
rockets to Mars are being sought. Thus there are many opportunities for
things to go wrong.”

“Over the years, inside the DOE labs, hundreds of workers have been
contaminated while fabricating space nuclear devices. It is not just
some theoretical chance of a space launch accident that we are concerned
about. We oppose the entire space nuclear power production process,” he
said. “It’s all dangerous!”

“Just like here on Earth there is a tug-of-war going on between those
who wish to promote life-giving solar power and those who want nukes,”
said Gagnon. “That same battle for nuclear domination is being taken
into the heavens by an industry that wants more profit—no matter the
consequences. The Global Network will continue to organize around the
space nuclear power issue by building a global constituency opposed to
the risky and unnecessary nukes in space program.” The Global Network is
based in Maine.
